Today s garage doors with polyurethane insulation will have an r value of 12 18 garaga s residential garage doors provide up to r 18 but you also want to choose a door that has otherwise good construction.
What r value should you look for in a new garage door.
A value of r 16 offers a 5 reduction in heat flow and a 5 improvement in energy efficiency over an r value of 8.
When it comes to r values for garage doors the higher the better.
R values climb as thickness of the material increases.
However you also need to analyze the door s cold resistance before making a purchase decision.
If your garage is not detached then the garage is probably insulated and you ll want a garage door with an r 12 value.
The higher the r value the greater the insulating properties of the door.
Between 9 18 4 the difference between the r values is caused by the thickness of the doors 1 model is.
Another thing that effecting the r value is the material of the insulation.
Attached but not actively heated or cooled garages should have a garage door with an r value between r 6 and r 9.
See chart for r value comparisons.
1 3 8 and the other model is 2.
